NRF52 / CMSIS not configured correctly

[lidiriel]

Describe your environment
Sloeber IDE
Sloeber version number : Linux 4.4.3 Latest Stable
OS: [debian 13.2]
third party index url : https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json

Config board
platform : seeedstudio / NRF52
board : Seeed XIAO nRF52840 Sense

Describe the bug
For a compilation of simple project there is a problem :
The CMSIS include not found :

eclipse/Sloeber/arduinoPlugin/packages/Seeeduino/hardware/nrf52/1.1.12/1.1.12/cores/nRF5/nordic/nrfx/mdk/nrf52840.h:147:10: fatal error: core_cm4.h: No such file or directory

For building I must had
$HOME/eclipse/Sloeber/arduinoPlugin/packages/Seeeduino/tools/CMSIS/5.7.0/CMSIS/Include in the C/C++ Paths and symbol properties.

after the linker didn't find the lib

/usr/lib/gcc/arm-none-eabi/14.2.1/../../../arm-none-eabi/bin/ld: cannot find -larm_cortexM4lf_math: No such file or directory

The seed stuff has been giving issues for a long time and I removed them from the testing as you can see here.

arduino-eclipse-plugin/io.sloeber.tests/src/io/sloeber/core/CreateAndCompileDefaultInoOnAllBoardsTest.java

Line 87 in d17ae32

Is it working in the Arduino IDE?

Hi jantje, It's working with the Arduino IDE. I can help to resolve this but I have no idea where is the problem !

[jantje]

What needs to be done is look at the differences between the command lines executed by arduino IDE and Sloeber.
Once these differences are identified I can look at why these differences exist.

EDIT:
I'm talking about functional differences (like missing defines, includes,...) not about actual differences (like different locations)
